The customer is responsible for supplying clean, dry fuel to the engine. Fuel filters are no less important than air filters to protect gas engines from dirt and debris. A proper fuel filter removes impurities that can damage the internal components of the engine. |
The gas must be supplied to the engine at a pressure that is acceptable. For optimum operation, use a fuel filter that is properly sized for the gas pressure.
For many gas engines, fuel filters are a provision of the design for the application. These devices are included in the normal maintenance of the plant. Therefore, Cat does not include a standard fuel filter as a part of each gas engine. However, fuel filters are available from your Cat dealer.
Note: Use a fuel filter that is designed to capture a minimum of 99 percent of the particles that are 1 micron in diameter.
Consult your Cat dealer about the requirements for filtering your fuel.
